It consists mainly of maltotriose units linked through α-1, 6 - glucosidicbonds. The average molecular weight is 2×105 Da. Pullulan can be developed into various products. It is an excellent filmformer, producing a film which is heatsealable with good oxygen barrier properties. It can be used widely in both the pharmaceutical and food industries, such as encapsulating agents, adhesives,thickening, and extending agent. Pullulan has been used as a food ingredient for over 20 years in Japan. It has Generally Regarded As Safe .PropertiesPullulan is non-toxic, non-mutagenic, odorless, tasteless, and edible. Dry pullulan powders are white and non-hygroscopic and dissolve readily in hot or coldwater. Pullulan solutions are of relatively low viscosity. The viscosity of pullulan solutions is stable to heating, changes in pH, and most metal ions, includingsodium chloride.ApplicationsPullulan can be used as either an innovative or decorative film or used in granule form for:Tabletting: Pullulan is an excellent tabletting excipient.Pan coating: Pullulan with its excellent adhesive properties and extremely low viscosity is ideally suited for pan-coating chewing gum，chocolate and candies.Agglomeration: Pullulan has about double the adhesive strength of food starch. This property combined with its lack of flavor enables it to be used effectively intypical agglomeration processes.Sauces and dressings: Due to its ‘adhesive properties’ use of granular pullulan in sauces improves their ‘on product’ retention without unduly increasing sauceviscosity.Innovative soft candy: Incorporation of 2-3% Pullulan, enables innovative soft chewy candies to be made by a cold extrusion process without resorting toconventional boiling. This enables heart sensitive materials to be used in these products.Coatings: Pullulan solutions which are odorless and flavorless can be used as a coating for a wide range of food products to improve appearance, reduceblemishes and increase shelf life.Capsules: Pullulan can be formed into capsules for use with pharmaceutical and nutraceutical products. Its non-animal origin ensures there are no safely concernswith consumers and it is suitability for all consumers groups.Packing: 10 kg / box 、20 kg / boxPullulan APIs & Food Additives
